C#/ NHibernate有注释吗？

// 定义一个 Person 类
public class Person 
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}

// 创建一个 Person 实体
// NHibernate 会自动映射并生成对应的数据库表
Person person = new Person { Name = "John Doe", Age = 30 };

<hibernate-mapping>
    <!-- 定义一个 Person 类 -->
    <class name="Person" table="People">
        <id name="Id" column="Id" type="int">
            <generator class="native"/>
        </id>
        <property name="Name" column="Name" type="string"/>
        <property name="Age" column="Age" type="int"/>
    </class>
</hibernate-mapping>

<hibernate-mapping>
    <!-- 创建一个 Person 实体 -->
    <entity name="Person" class="Person">
        <id property="Name" column="Name" type="string"/>
        <id property="Age" column="Age" type="int"/>
    </entity>
</hibernate-mapping>
